VSWR control and application analysis in high-speed micro-coaxial signal link: HRS DF36-20P-0.4SD

In the field of high-speed signal transmission, extremely thin coaxial cables (Micro Coaxial Cable) are widely used in precision equipment such as intelligent security, drones, medical imaging, and consumer electronics. The quality of signal transmission largely depends on the VSWR (Standing Wave Ratio) indicator. The HRS (Hasegawa) DF36-20P-0.4SD, with its precise structure, reliable shielding, and high grounding performance, provides a stable high-speed interconnection solution for ultra-thin coaxial systems, and is a key component for controlling VSWR and ensuring signal integrity.

I. Main Features

DF36-20P-0.4SD belongs to the HRS DF36 series of 20-pin miniature components, with a pitch of only 0.4 mm, suitable for ultra-thin terminals and miniature modules. It features an ultra-small size, a metal shielding shell, a high-precision positioning structure, and multi-point grounding springs, which can effectively suppress EMI interference and ensure connection stability. This product is widely used in scenarios with high requirements for high-speed signals and stable transmission, such as camera modules, medical probes, industrial lenses, and portable terminals.

The importance of VSWR

VSWR (Standing Wave Ratio) is an important indicator for measuring the impedance matching degree of a transmission system. The closer the VSWR is to 1:1, the less signal reflection there is, and the more stable the transmission is; the higher the VSWR, the more signal reflection increases, which is likely to lead to transmission losses or system instability. In extremely thin coaxial cable systems, due to the extremely small wire diameter, even slight deviations or impedance mismatches can cause a significant increase in VSWR, thereby affecting the high-speed signal performance of the entire device. Therefore, controlling VSWR is a key factor that must be paid attention to in the design of micro coaxial systems.
